Can EE keeper/NI be used to implement Wild Mage Spell Progression Tables?

Hi

After some playing around with EE Keeper, I've managed to dual-class a character from a thief TO a wild mage, with very few issues that I can see so far. Wild surge is working. -/+ casting spell levels are working. Spells are memorised, etc. The only problem I have is spell memorisation. My wild mage is set on the spell progression table of a trueclass mage, meaning it doesn't get the +1 spell slot per level.

This is a recurring theme amongst the community of those who have experimented with this class combination in the past. However, most of the posts I have been able to find on this subject have been a few years old. I am wondering if anyone has by now found a solution to this? If you could post it here it would really help me out.

Edit: If there is no way to do this with EE Keeper, can it be done with Near Infinity?
